A single feed dual-band (2.4GHz/5.8GHz) miniaturized patch antenna for wireless local area network (WLAN) Communications

In this paper, a single layer, single feed, dual-frequency microstrip patch antenna is proposed. This antenna was design for IEEE 802.11b (2.4GHz~2.4835GHZ) and IEEE 802.11a (5.725GHz~5.825GHz) frequency bands. Its dualband behavior is achieved by a shorting pin at 2.4GHz and 5.8GHz. In addition, the antenna is miniaturized by 31.8% compared to the conventional rectangular patch without a slot. This antenna has a broadside and symmetrical radiation pattern suitable for wire local area network (WLAN) applications.
